yes. yes he did. i’m also gonna direct you to the real life ‘lord of the flies’ which occured in the 1960s, when six tongan schoolboys got stranded on a desert island for over a year before being rescued by an australian fisherman (who, it should be noted, later took on all six as crewmembers because the reason they were out in the first place was because they wanted to see the world, and named his ship the Ata after the island they were stranded on). nobody died. the only injuries that occurred were accidental, and when one of the boys broke his leg falling down a cliff, the others braced it and looked after him so well that it healed perfectly. if they argued, then they would literally go to opposite sides of the island until they’d cooled off. after leaving the island, they remained friends for the rest of their lives. here’s a photo of them as adults, with their rescuer (who is third from the left) and other members of his crew.
i read about this in rutger bregman’s human kind, a book i cannot recommend highly enough, but if you don’t want to go and read a whole book about the inherent goodness of humanity (which again, you really should) then the relevant excerpt can be found here.
